How to add a person to scrum board without email address

[bunny boo]

I'm using the free trial of Jira to see whether it will suit my business needs.  How do I add a person to the scrum board as a test, without having to enter a valid email address.  I just want to test Jira and see whether it's suitable for my needs, without having to setup the scrum board with valid email address

Hi @bunny boo ,

you can create another user in your jira instance with the same email-address as yours.

The username must be different, the email not.

I have the same question but I'm not sure how you create another user with the same address but different username.  Can you please provide some steps.  Thanks!
